Improvement in car-couplings



UNITED STATES LAMPERT SCHMID, OF

IMPROVEMENT IN ALBANY, MINNESOTA.

cAR-couPLlNGs.

Specification forming part of Letters Patent No. 151,919, dated June 9, 1874; application filed February 4, 1874.

To all whom it may concern Be it known that I, L. SGHMID, of Albany, in the county of Stearns and in the State of Minnesota, have invented certain new and useful Improvements in Car-Couplings; and do hereby declare that the following is a full, clear, and exact description thereof', reference being had to the accompanying drawings and to the letters of reference marked thereon, making a part of this specification.

The nature of my invention consists in the construction and arrangement of a car-coupling, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figure 1 is a bottom View, and Fig. 2 a lon gitudinal vertical section, of my car-coupling.

At one end of each car are two longitudinal beams, A A, placed a suitable distance apart and parallel with each other. To the under sides of these beams are fastened suitable boxes a a., in which is placed a rocking shaft, B, and upon this shaft are secured two arms, C G, placed parallel between the beams A A, and connected together by top and bottom cross-bars a a. The arms C C project a suitable distance in front of the end of the car,

and through their front ends is passed a pin or bolt, D, secured by means of nuts Z upon its ends. E represents a spring to bear upon the top cross-bar a', to hold the bars C C downward in a horizontal position and upon a guideframe, d, which prevents the arms or bars C C from goin g below thehorizont-alposition. Upon the oppositeend of each car is a beam, G, with an upward-projecting hook, h, on its front end. H is a bumper arranged above the beam G at the end of the car.

In bringing the cars together, the front beveled side of the hook h strikes the bolt or pin D, and raises the same with the front ends of the arms O C until the point of the hook has passed from under the bolt, when the spring E throws the arms C C downward again, so that the hook will catch on saidl bolt.

To uncouple the cars, the arms C C may be raised to bring the bolt D above the point of the hook by means of a vertical shaft, I, from the platform of the ear, or by a horizontal shaft from the side of the car.

This device is self-coupling, and will never uncouple itself as long as the cars are on the track; but if one car should get'off from the track it will uncouple itself, leaving the others 011 thet-raek.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

rlhe combination of pivoted arms C C, with cross bars a! a', pin D, spring E, and beam G, with hook IL, all substantially as and for the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 19th day of January, 1874.

LAM PERT SGHMID.
